Galactic disks are giant, rotating structures composed of stars, gas, and dust within galaxies. They are typically flat in shape and contain a large portion of a galaxy's mass. Galactic disks play a crucial role in shaping the morphology and dynamics of galaxies, as well as in the formation and evolution of stars. Research on galactic disks often focuses on understanding their structure, stability, kinematics, and interactions with other components of a galaxy, such as bulges or halos. Studying galactic disks can provide insights into the formation and evolution of galaxies, as well as the processes involved in star formation and galactic evolution.
